Mh, should be doable with the dpad widget. I’ll install the free version and check.
Edit: ah now, that’s not supported in the free version. I’ve tried with the paid version though. It sort of works, but the mouse navigation via dpad is limited in the way that it moves the nouse cursor to the screen edge, and then stops. So you can only turn around for maybe a quarter or half turn, then it stops.
I’ll try to figure out something else. Maybe anyone else has an idea?
